Final answer:
The end product of the synthesis of saturated fatty acids is triglycerides, which are formed by joining fatty acids to a glycerol backbone.
Step-by-step explanation:
The end product of the synthesis of saturated fatty acids is triglycerides. Saturated fatty acids contain no carbon-to-carbon double bonds, allowing them to pack closely together and typically be solid at room temperature. These fatty acids are joined to a glycerol backbone through a process called dehydration synthesis, forming triacylglycerol, also known as triglycerides. This molecule consists of three fatty acid chains connected to a single glycerol molecule, which is a key component of body fat in humans and animals as well as vegetable fat. These triglycerides are stored in adipose cells and can be used for energy at a later time.
